Changelogs have to explain the WHY not the WHAT. What the patch is doing
is already in te subject line and the exact WHAT (implementation) is in
the patch itself.

This applies to all 4 patches in this series. Each wants to have an
explanation of why this makes sense and which problem this is trying to solve.
